Eaton DH221NGK - 30A, 240V, Fused Disconnect Switch

Eaton DH221NGK — a 30A, 240V fused disconnect switch engineered for dependable electrical isolation in demanding industrial and commercial environments. This compact, purpose-built unit combines rapid disconnect capability with built-in overcurrent protection, ensuring safe maintenance and reliable operation under load.

What makes the DH221NGK stand out is its practical integration of fusing directly at the disconnect point. This design supports clean lockout/tagout procedures, minimizes downtime, and reduces the number of separate components you need to manage in control panels, motor starters, or equipment enclosures. Built for long-term durability, it maintains consistent performance even in busy facilities where electrical reliability is essential.

Key benefits

• provides immediate overcurrent protection at the disconnect, helping to shield downstream wiring and components from faults.
• 30A at 240V rating suits common motor control circuits, pumps, and other industrial loads without oversizing or under-protecting the circuit.
• NEMA 1 enclosure offers reliable indoor protection against dust and basic environmental contaminants, ideal for general-purpose installations.
• Safe under-load disconnection capability ensures you can isolate equipment during operation when required, reducing risk during servicing.
• Lockout/Tagout compatibility to help facilities meet safety standards and keep maintenance personnel protected.

Ideal use scenarios

• Motor control sections in manufacturing lines, where quick, secure shutoff is essential for routine maintenance.
• Industrial machinery and process equipment that demand reliable isolation to perform service safely.
• Commercial HVAC, pumps, and related control circuits that require tamper-resistant disconnection with built-in protection.
• Maintenance workflows in facilities management where clear, compliant lockout/tagout procedures are a priority.

Why choose this over non-fused options

With the DH221NGK, you gain not only a disconnect but also integrated protection. The fused design mitigates fault energy at the source, reducing the likelihood of downstream damage and nuisance trips. This simplifies wiring, improves safety during servicing, and supports leaner maintenance routines without sacrificing protection or reliability.
